FILE – A man pumps gas at a Mobil gas station on Western Avenue in Chicago on, Jan. 4, 2017. The price at the pump is $1.30 higher than a year ago. Industry analyst Trilby Lundberg of the Lundberg Survey said Sunday the rise comes as the cost of crude oil and ethanol surges. Nationwide, the highest average price for regular-grade gas is in the San Francisco Bay Area, at $4.77 per gallon. (Antonio Perez / Chicago Tribune)
